We're not still adding to the periodic table. https://en.wikipedia.org/wiki/Oganesson , 118, was synthesized in 2002, and confirmed in 2015 and I don't think anybody is actively working on making https://en.wikipedia.org/wiki/Ununennium or https://en.wikipedia.org/wiki/Unbinilium for lack of resources right now.

If somebody is aware of groups actively working to synthesize above 119 please let me know.
